ADJUSTABLE LINER FOR TYPE-CASTING MACHINES.

Specification of Letters Pateht.

Patented May 18, 1920.

T0 all whom t may concern.'

Be it known that I, GEORGE A. JoNns, a citizen of the United States of America, residing at Baldwin, Long Island, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Adjustable Liners for rlype- Casting Machines, of which the following is a specilication.

This invention relates to liners for molds of type-casting machines, and also to certain combinations of said liners with other parts of type-casting machines and aims to provide improvements therein. n

In the casting of slugs for type or lines of type, it is necessary to adjust the height of the mold space for slugs of different point or height, and also to adjust the width of themold space for each different width of slugs (corresponding to different widths of column) to be set up. In order to simplify the description, however, the invention will be hereinafter particularly de; scribed with reference to use in the casting of slugs for lines of type.

The height of the mold space is usually adjusted by substituting` liners of different height, that is, by substituting a different liner for each point of type used. And the width of the mold space is usually adjusted by substituting one of the liners (of a pair) for another of similar height but of different length, depending on the width of the mold space corresponding to the width of column desired.

Therefore, to provide a type-casting 1na chine with a mold space adjustable to the various height or point of type, and to the various column widths met with in actual practice, requires the owner of a type-casting machine to keep on hand a very large number of liners, which liners are relatively costly.

The present invention provides a liner which takes the place of a number of liners, and which is usable in modern machines, with all the advantages of present liners. The present invention reduces, to a very largeeXtent, the number of liners heretofore necessary in order to adjust a mold space to its full capacity as to height and width of the slugs cast therein, as two, at most, of the present adjustable liners will take the place of 51 ordinary liners in a 30 em mold.

The invention further provides a liner which may be placed in position and removed with minimum effort.

An embodiment of the invention is illustrated in the accompanying drawings.

In said drawings:

Figure 1 illustrates the front of a mold, as usually constructed.

Fig. 2 is atop plan view of an adjustable liner embodying the present invention.

Fig. 3 is a rear elevation of the liner shown in Fig. 2.

Fig. 4; is a sectional view of the liner shown in Fig. 2.

Fig. 5 is a view similar to Fig. 2 of another' form of liner embodying the invention.

Fig. G is a sectional view of the liner shown in Fig. 5.

Fig. 7 is a. top plan view of a liner used opposite the adjustable liner.

Referring to the drawings, A designates a mold, such as usually employed in type-cast ing machines. This mold is shown as mounted upon a rotatable mold disk, but it is not essential that the mold be so mounted.

The mold usually comprises a mold base 1%, a mold cap C, and liners D and E, the

liners D and E being clamped against the base by latches F, F, which draw the parts together.

The liner E preferably occupies a definite position at one side of the mold, the liner, for this end, being conveniently provided with holes e, e2, in which fit short pins or studs e3, e4, projecting from the cap C and base B, respectively. The liner E is also usually provided with a notchl es, through which the latch F passes.

The liner E is placed opposite the liner wD, and the space formed between these liners constitutes the mold space in which the slug is cast, the face eT of the liner E, and the face (Z3 of the liner D forming the sides of the mold space, the front e8 of the mold space being closed during the casting of the slug by a line of nia-trices, and the rear e9 of the mold space being closed by the lip or face of the pot containing the type metal, which pot is moved into contact with the rear of the mold prior to casting the slug, and from which pot the metal is forced for casting the slug, the said lip or face of the metal pot being usually provided with a series of small orifices, the

series having a 'width corresponding to the maximum width of the mold space as indicated at p, p. *Referring particularly to Figs. 2 to 6, inclusive, thel adjustable liner forming the subject of the present invention, and designated by reference letter D, is most conveniently formed in two parts UZ, Z. The part Z is adapted to occupy a fixed position in the mold, and the part Z2 is movable with reference to the part Z, in such manner as I to vary ythe width of the mold space.

AVextending part Z For fixing the position of the part Z it is conveniently formed with a hole or recess Z'L adapted to fit a pin or stud Z5 projecting from the mold base B. The part Z is also conveniently formed with a recess ZG through which ythe latch F passes.

The part Z2 is provided at its rear' side with a Vlongitudinally extending part Z7, which part 7 has a rear face ZS which is ladapted to cover and shut off the flow of metal from all of the orifices of the pot lwhich are not opposite the mold space between the faces Z3 and c7 of the liners D and E. The part Z7 and its face ZS, lare also of suiiicient length to entirely cover all oi' said orices in the lip or face of the pot (except those between the faces Z3 and eT of the mold space), when the part Z2 is adjusted inwardly to` provide a minimum width of mold space within tlielimits of A adjustment of the liner. As will be explained hereinafter, it is not alwaysY possible to provide for-all of the adjustments of width of the mold space with a single adjustable liner, but the whole range of adjustments of width of the mold space can usually be provided for with two adjustable liners. If the working parts of the machine admit of it, there is no .reason why a singlev adjustable liner cannot be made to take care of all the adjustments of width of the mold space of the machine. The face Z9 of the extension Z7,-and the face Zlo of the part Z convenientlyform a guide for n the part Z2 in its adjustments in the mold.

Preferably the part Z2 has a longitudinally kextending part Z12 at the front of the liner, correspondingto the longitudinally These two longitudinally extending parts Z7 and Z12 preferably Ylit closely the facesV Z9-and Z1g of the part Z, so thata good guidingV effect of the part Z2- .on the part Z is obtained.y There is also preferably a rib and slot connection Z15, 7,16, between the parts Z and the extensions Z7, Z12 of thepart d2, vthough the liner may be Vmade with other formsof connection, lor

evenl without connections.

In order that the liner Z may befirmly clamped in themoldbetweenthe 'base B and the cap C, it is preferably tapered at .oneof-its upper or lowerv faces, from its inner to its outer end, viz., the width dea yVernier, whereby Y the slug.

end, is conveniently recessed, as indicated at Z1S, and the'end of the part Z is also correspondingly recessed upon vits upper face, as indicated ataZlD, and the position- Ying hole or recess Z4 is formed in this portion Z19 of the part Z. This construction enables the parts Z and Z2 to telescope to the maximum extent, and also preserves the strength of the parts.

In order to conveniently determine the V,exact width of the mold space, and also to conveniently carry out adjustments, the relatively movable parts Z and Z2 are provided one with a datumr mark and the other .with suitable graduations, as for example, yeins of type. Moreover, a plurality of datum lines may be provided on principles of extremely accurate adjustments 'may be made.-

Yperation: In casting slugs of any particular width, in order to change the machine for casting slugs of anotherwidth, it is simply necessary to loosen-or remove the mold cap and movethe lpart Z2 inward or outward with relation to the part Z, tothe desired extent, thereby Vadjusting the width Vof the mold space betweenthe faces Z3, ef, Yof the liners D and E. TheY mold cap is thereupon tightened orv replaced, and the mold is ready for 'having cast therein slugs of the new width. VThe extension Z7 serves to shut oft" all of the'perforations p in the face or lip of the potl containingr the molten type metal, which arenot opposite the space in the mold between the Afaces (Z3, c7 of the liner, and thereby prevents any part of the mold or 'liner being fouledby metal from the pot which'is vnot necessary fory casting After the slug is cast, it is, asusual, separated from the metal in the pot, shaved or trimmed and ejected. v

It is Vobvious that the inventive ideas herein set forth may receive'other mechani-V cal expressions than those herein specifiucally illustrated and described..V
